Professional Opinion of Dr. Mario Dumitrascu,
It has long been politically correct to state that it's "not the size but the motion" that counts. Women have so long been under the thumb of religion and patriarchy and most women have learned that lying to "your man" is much more fruitful/profitable than denigrating him because of his lack of penis volume. And what good would discussing about penis size do anyway, it's not like a guy can change it. It is a done deal and it's simply not worth mentioning about it once in a couple context.
However, that being said, that point of view in no way dictates that biologically speaking, the penis size is unimportant. The vagina is an elastic structure and responds differently to various shapes and volumes. In addition, most studies indicate that the the penis size to total body ratio is a fairly good indicator of female sexual selection in nature. And Homo sapiens males are very well endowed indeed in this regard, favoring a view that in Homo sapiens females do exercise choice (evolutionary speaking).
THE AUTHENTIC WOMEN’S PENIS SIZE PREFERENCE CHART
The following graph,shows that women's response to penis size is variable. It also demonstrates that "bigger" is not "better" in the absolute sense. But what it does support is that size is relevant. The important number to consider is that accross the board, beyond races and nationalities and age, the average male is between 5.5" and 6" in length erect. So when women are asked if they 'fake orgasm' and stats reveal that a whopping 50% of females have faked it and when we look at where that 'average' size fits on this graph, we can guess at the 'faking it' motivations. Our size range is simply incompatible. As for girth, I think we can simply say that if your fingers touch when holding the penis in your hand, it is on the narrow side. A mere little can of Redbull is 7" in circumference, and a regular soda can is close to 8".
RACIAL FACTORS IN PENIS SIZE
Despite reinforcing every ethnicity-based penis stereotype imaginable, the map below does contain a few surprises, like that the world's most powerful nations seem to be the least powerful where it counts.
